  • Publication number: 20070271976
    Abstract: Apparatus and associated methodology are provided for key operated pin tumbler locks, some of which may incorporate a removable core pin tumbler lock. A selected tumbler of a type commonly used in pin tumbler locks is configured along with a driver pin to control operation of a retainer that, when rotated by use of a control key inserted in the lock, allows alternate selective removal and replacement of the core assembly in the lock. Also, or separate therefrom, one or more tumbler holes may be formed or drilled in a manner so as to prevent engagement of a tumbler with the bite of a key. Presently disclosed structures and associated methodology help to reduce any susceptibility to unauthorized techniques practiced against the lock, such as unintentional activation of the tumblers by unauthorized persons through use of a key with so-called “bumping” techniques.

  • Patent number: 6085560
    Abstract: A pin tumbler mechanical lock includes an electronic component incorporated in the key which connects to an axial lead aligned to mechanically engage the spring biased contact of the key whereby in order to operate the lock both the mechanical pin tumblers and the electronic signal provided by the key are necessary.

  • Patent number: 5846577
    Abstract: A continuously operating press for pressing a web of material together has a press zone at an input side a calibration zone at an output side. This press may be used in the formation of particle board by applying heat and pressure to press the web of material together to form the particle board. Preferably, the press has a lower press platen and an upper press platen that are pressed together to form the particle board. Both the lower press platen and the upper press platen preferably have a PTFE composite pressure pad. This composite pressure pad may have a layer of virgin PTFE and a layer of filled PTFE. The layer of filled PTFE is preferably partially compressed at a pressure of about 14.7 psi. After which, the layer of filled PTFE is preferably compression molded with the layer of virgin PTFE to form a composite. This composite may also be sintered and coined.

  • Patent number: 5670189
    Abstract: Methods of compression molding powdered polytetrafluoroethylene resins to produce composite articles of manufacture having at least two distinct layers of two types of PTFE resin are disclosed. A first layer of resin, preferably including a filler, is placed in a compression mold and partially compressed at a relatively low pressure. A second layer of resin, preferably virgin resin, is then added to the mold and both layers are simultaneously fully compressed. After compression, the resulting composite preform is preferably sintered and coined to create a finished PTFE material or product. In a preferred embodiment, the partial compression step is performed at pressures of less than 500 psi. It has been found that modified PTFE resins provide improved resistance to cold flow and also provide better binding between filled and unfilled (virgin) layers and thus are used in certain preferred embodiments.

  • Patent number: 5458382
    Abstract: A deadbolt latch assembly capable of accommodating both rectangular faceplates and circular faceplates. The latch housing assembly is provided with a semi-permanent rectangular faceplate assembly attached thereto, but which is removable with a prying tool to allow the housing to accommodate an alternative faceplate such as a circular faceplate. The housing is manufactured of a thick walled steel casing to enclose and retain not only the latch but the latch extension as well, to thereby prevent the latch extension from flexing about the latch-extension joint.

  • Patent number: 4372798
    Abstract: An electrostatic field is created across a layer of material which has been placed on a surface with an adhesive layer therebetween to force the layer of material toward the surface, compressing the adhesive therebetween. To carry out this process, various forms of apparatus are disclosed which provide a substantially consistent electrostatic field across a film of material and a coating of adhesive to a surface to which the material is to be secured.

  • Patent number: 4085892
    Abstract: A continuously energized electrostatic spray coating system sends measured masses of highly conductive coating material across an insulating air space from a grounded pulser to a high voltage container. A series of such continuously energized voltage blocks have their output connected to a manifold which is alternately supplied paint from one of the voltage blocks by remote control.
